This study investigated relationship between bone marrow perfusion and bone mineral density (BMD) at proximal femur over 4 years. Dynamic contrast enhanced MRI data was extracted pixel-by-pixel and classified into 3 patterns to indicate the perfusion function. For the subjects with good bone marrow perfusion, their BMD would keep stable after 4 years, while for those with bad perfusion, their BMD consistently decreased over 4 years. The results indicated that the perfusion function could have a long term effect on BMD and a good perfusion function would help to keep the bone health.
